He already is my sub, so I don't really need to think about this.
Now if he switched roles and decided to be the dom for once...<w<
As a switch myself I've had quite a few daydreams where we swap roles but for now he's too timid to try that.
I figure maybe a few years after we start actually getting to see each other in person (it's an LDR, he's way down in Florida) then maybe he'll get sort of curious and try being the dom for a change of pace.

She is my sub.
We try to switch roles from time to time.
She does not like to 'lord over' (as she calls it).
She always gets mad because I am screaming harder, harder, HARDER! And she is giving it all shes got.

I'm the sub and I'll always stay that way. I don't have any ounce of dom in me. Every time I ever tried when I first got with my partner, I was just so timid and shy and soft that it just never worked for us.

I wouldn't ever take advantage of someone being my submissive. However, if they had the stupidity to petition me for a day only, then I would probably tell them to do whatever they wanted to themselves and leave me alone.

I'd tie him down. Spank him hard, bare handed. Call him names. Run needles in a circle and then use my nails on the sensitive spot in the middle until he squirmed. Another spanking, with a paddle. Make him give me oral, just because I could. Use the belt when he couldn't make me orgasm. There also might be a strap on involved somewhere.

Then I would realize how deep the trouble I'd be in when we switched back, and run away. My Dom is a sadistic bastard, and I love it!
